In view from you
Nobody watches DSP F19 go over, but a receiver still asks whether it is above the horizon. Say where you are and this card answers.
Your position is rounded to about a kilometre and sent only to the Orbinauts API, to find the pass.
No brightness has been published for DSP F19, so it is not a naked-eye satellite and no city page carries pass times for it. Nothing here estimates one.
Seeing it
There is nothing to go outside for: it is too faint to see with the naked eye from anywhere on Earth.

No operator publishes an ephemeris for DSP F19, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to DSP F19 has been reported publicly in the past thirty days.
From Space-Track’s public conjunction messages; the latest report was issued Nov 8, 2026, 1:11 PM, 3 hours old. Only approaches serious enough to be reported publicly are listed: within three days and, for two bodies near the Earth, closer than a kilometre with a chance of a collision above 1 in 10,000, the level at which NASA moves the ISS.
Launched with
DSP F19 shares its launch, 1999-017, with 3 other bodies the catalogue lists in orbit.
| Body | What it is |
|---|---|
| IUS R/B(1) | Rocket body |
| IUS R/B(2) | Rocket body |
| USA 142 DEB | Debris |
Read from the international designators of the US catalogue: the year and the launch number every piece of one launch shares. A body that has come down is no longer listed.
